The invention consists use ot'a seriesof amalganlated plates, secured at properdistances apart and connected .withj any suitable moving parts, .which will adf minet'v the amalganated. plates being drawn: through the pulp, as hereinafter set forth. .l

A represents a wheel, which may be constructed of cast-iron and formed with a broadi tread or periphery, a, extending somedis tance each side of the body or main portion b.

To cach side of the body or main portion b of the wheel there are attached a series ot' copper plates, B, which may be in the for'in ot' quadrants,`and secured to b byaneans ot' bolts c, .having washers d on them to keep them at a proper distanceapart' and admit ot' a t'ree l or open space between theV several plates, so 5 that both sides ot each, except the inner ones, l which are in contact with b, may be brought, in contactv with 'the pulp, a space, e, being] allowed between the edges ot' the severa-l sets 5 of plates, as shown in.

Any number of-these plates B may be used'in forintwo functions-to wit, a crusher land anv amalgarnator.'

`he copper plates B, previous to beingused, have their .surfaces properly ainalgainated with quicksilver, and the wheel Af,\ "while being drawn around trough containing the pulp and quieksilver, will cause the, plates B to pass through the latter, and `said plates will catch and amalgainateallthe particles of gold which may come .in-contact with them.; that I. obtain an amalgamating devicewhich to what is'now employeihjand without mouopolizing anyaddi- .tionalf sp'aceor 'oomfandj-Qwin g to "th'1s`"a'r.' rangement, the g'old centalnedn th piilp izwilL be eifeetuallyseparated fromli t, tl 1 -tine pr'tielels,-whichfare light and rise tbv'the surface and frequently 'pass fout with. the water, beingarrested and amalgamated 'with `the plates, C,"which arc other bybolts f, havto keep the plates C at a proper distance apart.

This drag may be connected to the axle j of the wheel A, or connected to any moving part ot' the device to enable it to'bo drawn through the pulp.
